Tensegrity Structure in a form of struts and cables owns important characteristics such as lightweight, self-stressed, flexible and controllable. The design of tensegrity system is different from the traditional systems with continuous transmission of compression. In tensegrity system, the tensional network (i.e. cable) is assembled in order to support the “floated” (or discontinuous) compression (i.e. struts). Tensegrity structure maintains its shape through self-equilibrium and its ability to stand without any supports under gravitational load is proven. Although the study on tensegrity system only started since 1950’s, the development and extensiveness of the study has fruitfully contributed to new independent branches of studies. Tensegrities has gained enormous interests in architectural, civil engineering, space engineering, sculpture construction, biology and recently in the robotic and automation community.
In the first part of her talk, the speaker will give an overview on the tensegrity structure, in terms of the brief history, principles, design concepts and several important applications. Tensegrity mimicking biological systems namely bio tensegrity is one of the important applications. Principle of bio tensegrity has been well adapted to living organism structure even in micro level like cells. The speaker will share her research work on the shape change analysis of bio tensegrity models mimicking human spine, in the second part. Basic assumptions, computational strategies and the important findings from the research will also be presented.
The objective of the talk is also to give a better understanding for our young engineers and practicing engineers to get some insight on the above topic.
